A dependency update is high priority if it satisfies one of following criteria:

The current version is behind the later version for over 180 days, e.g. com.google.auto.service:auto-service 2014-10-24 -> 2017-12-11.

In Beam, we make a best-effort attempt at keeping all dependencies up-to-date.
In the future, issues will be filed and tracked for these automatically,
but in the meantime you can search for existing issues or open a new one.
